Assembly.
Install
the snap
ring
(fig. 14) in the bearing support. Install the clutch sleeve in the bearing
support with the large end of the sleeve facing toward the bearing
cup end of the bearing support. Install the bearing and snap ring in
the bearing support. Install the interlock spring and ball. Depress the
interlock ball, then push the shift rail into the bearing support until
the threads on the rail are flush with the bearing support. Hold the
shift rail stop in position in the bearing support and push the shift
rail into the shift rail stop. Install the nut and lock washer on the
shift rail.
e. Transmission
Cover. If the shift lever has been removed, rein-
stall it, securing with a lever pin. This pin should be installed with an
arbor press or bench vise. Install the safety latch plate. Place spring
(7227) in position as shown in fig. 15. Slide the gearshift lever through
the spring and safety latch plate and turn it 90 degrees until the pin
is properly seated in the slot in the bottom of the cover. Compress the
spring and install the spring retainer (7228). Position a new gasket
on the starter switch and install the switch in the cover, Place the

the housing and install the reverse idler shaft and lock ring. Position
the countershaft assembly in the transmission housing with the large
gear at the front of the housing. Install the countershaft front bearing
retainer and gasket. Hold the countershaft in position and install the
power take-off shift assembly together with the shim pack which was
previously removed and identified. Install the power take-off shaft in
the shift assembly. Measure the torque necessary to turn the power
take-off shaft. It should be from
15 to 30 pounds-inches.
Add or
